It would be best to start with the new pages, and pages that are really usefull that are already there, let them conform to the template.But before doing something like this, we need to know what type of pages there are. Or maybe I am making it harder that should be.

That would be a good start; try to generalise what we already have out there. In no particular order...

-Hardware pages eg motherboards, z-wave device-User pages-Overview pages eg this is an MD, this is a core, the network must be set up like this because...-Instructional pages eg the procedure for adding a light, NOT hacks-hacks

There must be more. So let's decide upon types of page, and then a template for each of those. I suppose this all feeds into the conversation about wiki structure as well.
